Precision Ball Grades

Types of Ball Screws

By screw shaft, they are divided into precision Ball Screws, which are ground with precision (six accuracy grades from C7 to C0), and rolled Ball Screws, which are formed through rolling with high accuracy (three accuracy grades from C10 to C7). Also, a series of nut-rotating Ball Screws, which are optimal for usage based on nut rotation,

Precision Balls

Precision balls are defined by grade: The lower the number of the grade, the more precision to which the ball is manufactured. The typical distinction between a precision ball and a semi-precision ball is between grades 50 and 100, wherein the grade 50 is considered a precision ball and the grade 100 is not. This definition arbitrarily varies ...
